About
Sea King Aquariums has become Bellevue's destination for saltwater and reef keepers, a family-run aquarium store whose reputation pulls customers from across Western Washington — some driving two hours from Yakima just to walk the aisles. Owner Abel anchors the shop with hands-on expertise and a genuine love for the hobby, and reviewers single him out again and again for patient, unrushed guidance that's tailored to your tank, your experience level, and how much time you can give it. Staff like Aldo round out a team repeatedly praised for friendly, knowledgeable help in both Spanish and English.
The coral selection is the headline. Rows of immaculately maintained tanks hold everything from high-end collector pieces to affordable small frags, with anemones and a rotating mix that keeps regulars coming back. Saltwater fish, invertebrates, and crustaceans fill out the livestock, and customers consistently marvel at the health of every specimen — one longtime hobbyist noted this is the only shop where she's never once spotted a sick fish.
If you're shopping for corals, saltwater fish, or invertebrates for sale in Bellevue, WA, the cleanliness and quality here are tough to beat. Beyond livestock, Sea King stocks reef tanks, gear, supplies, and treatments — one visitor popped in for an algae treatment and found exactly what their saltwater tank needed — and the team also handles equipment repairs. Newcomers starting their first reef tank get walked through setup and species-by-species acclimation, while seasoned reefers come for the deals: a buy-three-get-the-fourth-coral-free punch card, frequent sales, and generous owner touches like holiday candy for kids and loyalty drawings.
It's the kind of saltwater aquarium store you build a relationship with — clean tanks, honest advice, and a community feel that makes every visit to Bellevue, WA worth the drive.

— Jennifer Lopez5.04 weeks ago“Great selection but the best part is the health of the specimens. Have been in several dozen fish stores over the years, but never have I seen a store with not a single sick fish. I always look, and always find a sick fish somewhere, but never at this shop. I’ve visited in person several times and now that I know how great the shop is, I’m just going to order online. If you ever find yourself in Seattle, be sure to visit!”
